Abstract
Description
Technical Field
[0001] This utility model relates to the field of conveying mechanism technology, specifically to a packaging box positioning and conveying mechanism. Background Technology
[0002] On an automated packaging production line, packaging boxes need to be conveyed while the automatic packaging operation is being carried out. Therefore, a conveyor belt is used. However, existing conveyor belts have difficulty in positioning packaging boxes at equal distances when conveying them, and it is also difficult to adjust the positioning spacing according to different sizes of packaging boxes. This makes it difficult for the conveyor belt to position packaging boxes of different sizes at equal distances, resulting in inconvenience in using the conveyor belt.
[0003] A prior art patent with publication number CN218560049U discloses a solution including a mounting frame. An internal drive shaft is rotatably connected to the mounting frame, and a drive motor is fixedly connected to one side of the drive shaft. A fixed frame is fixedly connected to the outer surface of the drive motor, and the outer surface of the fixed frame is fixedly connected to the outer surface of the mounting frame. A driven shaft is rotatably connected inside the mounting frame. The drive shaft and the driven shaft are connected by a conveyor belt. This solution, through the cooperation of the conveyor belt, mounting mechanism, and positioning mechanism, solves the problem that existing conveyor belts struggle to position packaging boxes at equal distances, and that it is difficult to adjust the positioning spacing according to different sized packaging boxes, making it inconvenient to use the conveyor belt.
[0004] The shortcomings of existing technology have gradually become apparent with use, mainly in the following aspects:
[0005] First, existing transmission and conveying mechanisms, such as belt conveyors and chain conveyors, have low positioning accuracy and rely on mechanical limiters or photoelectric sensors, making it difficult to meet the requirements of high-precision packaging.
[0006] Secondly, during the transportation process, when the existing packaging boxes need to be opened, the lids are prone to falling off the packaging boxes, affecting the stability of the bottle packing.
[0007] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content
[0008] To address the shortcomings of existing technologies, this utility model provides a packaging box positioning and conveying mechanism to solve the problem that traditional transmission and conveying mechanisms, such as belt conveyors and chain conveyors, have low positioning accuracy and rely on mechanical limiters or photoelectric sensors, making it difficult to meet the requirements of high-precision packaging. In the existing packaging box, when it needs to be opened during the conveying process, the lid is easy to fall off the packaging box, affecting the stability of the bottle packing.
[0009] To achieve the above objectives, this utility model provides the following technical solution:
[0010] The packaging box positioning and conveying mechanism includes two parallel rotating conveyor chains. L-shaped support seats are fixedly connected to the opposite links of the two conveyor chains. A partition is fixedly connected to the middle of each support seat, dividing the area on both sides of the support seat into packaging box corner support surfaces. The areas containing the four packaging box corner support surfaces form the packaging box positioning area.
[0011] One of the chain links is connected to a lid guide seat located within the packaging box positioning area, and the opposite sidewalls of the lid guide seat are respectively provided with guide grooves that match the opposite sidewalls of the lid.
[0012] As an optimized solution, a connecting positioning plate is fixed between two opposing support seats on two conveyor chains.
[0013] As an optimized solution, a connecting rod is fixed between the opposite sidewalls of the cover guide seat.
[0014] As an optimized solution, the two ends of the two conveyor chains are rotatably mounted on sprockets, which are rotatably mounted on the frame.
[0015] As an optimized solution, an opening stroke limit seat extending along the conveying direction of the conveyor chain is fixedly connected to the side wall of the frame near the cover guide seat. When the cover is opened, the outer end of the cover abuts against the opening stroke limit seat.
[0016] As an optimized solution, a linkage shaft is fixed between the two coaxial sprockets.
[0017] As an optimized solution, servo drive bodies that are connected to sprockets at both ends are fixedly connected to both ends of the frame.
[0018] As an optimized solution, the upper ends of the support base and the partition are respectively provided with a guide slope for the packaging box to fall into.
[0019] As an optimized solution, the cover guide seat is provided with a cover sliding guide slope at the inlet end of the guide groove.
[0020] Compared with the prior art, the beneficial effects of this utility model are:
[0021] Two sets of servo drive bodies drive both ends of the conveyor chain respectively, and the cumulative error of long-distance conveying is eliminated by combining synchronous control algorithm;
[0022] By forming a packaging box positioning area in the area where the four corner support surfaces of the packaging box are located on the conveyor chain, the packaging box can be accurately positioned and conveyed, satisfying the positioning operation of the packaging box in each process on the conveyor line;
[0023] By setting a cover guide seat on the side of the cover that is open, the opposite side of the cover slides into the guide groove when the cover is pulled out, which can effectively support and guide the cover in the open state and prevent it from falling.
[0024] An opening stroke limit seat is installed on one side of the frame. When the cover is opened, the outer end of the cover abuts against the opening stroke limit seat, thereby limiting the opening stroke of the cover. Attached Figure Description

Detailed Implementation
[0030] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.
[0031] like Figures 1 to 3As shown, the packaging box positioning and conveying mechanism includes two parallel rotating conveyor chains 1. L-shaped support seats 2 are fixedly connected to the opposite links of the two conveyor chains 1. A partition 3 is fixedly connected to the middle of each support seat 2, dividing the area on both sides of the support seat 2 into packaging box corner support surfaces 4. The areas containing the four packaging box corner support surfaces 4 form the positioning area of the packaging box 12.
[0032] One of the chain links is connected to a cover guide seat 7 located in the positioning area of the packaging box 12. The opposite side walls of the cover guide seat are respectively provided with guide grooves 9 that match the opposite side walls of the cover 13.
[0033] A connecting positioning plate 6 is fixed between two opposing support seats 2 located on two conveyor chains 1.
[0034] A connecting rod 8 is fixed between the opposite side walls of the cover guide seat 7.
[0035] The two ends of the two conveyor chains 1 are respectively rotatably mounted on sprockets, and the sprockets are rotatably mounted on the frame.
[0036] An opening stroke limit seat 10 extending along the conveying direction of the conveyor chain 1 is fixedly connected to the side wall of the frame near the cover guide seat 7. When the cover 13 is opened, the outer end of the cover 13 abuts against the opening stroke limit seat 10.
[0037] A linkage shaft is fixed between the two coaxial sprockets.
[0038] Servo drive bodies 11, which are connected to sprockets at both ends, are fixedly connected to both ends of the frame.
[0039] The upper ends of the support base 2 and the partition plate 3 are respectively provided with a guide slope 5 for the packaging box to fall into, so as to guide the packaging box 12 when it falls in.
[0040] The cover guide seat 7 is located at the inlet end of the guide groove 9 and has a cover sliding guide slope 14 to guide the cover 13 when it is opened, and to prevent interference and collision with the cover guide seat 7.
[0041] The connection method between the support seat 2 and the cover guide seat 7 and the chain link is common and not an innovation of this solution, so it will not be elaborated here.
[0042] The working principle of this device is as follows:
[0043] Two sets of servo drive bodies 11 drive both ends of the conveyor chain 1 respectively, and the cumulative error of long-distance conveying is eliminated by combining synchronous control algorithm;
[0044] By forming a positioning area for the packaging box 12 in the area where the four corner support surfaces 4 of the packaging box are located on the conveyor chain 1, the packaging box 12 can be accurately positioned and conveyed, satisfying the positioning operation of the packaging box 12 in each process on the conveyor line;
[0045] By setting a cover guide seat 7 on the side of the cover 13 that is open, the opposite side of the cover 13 slides into the guide groove 9 when the cover 13 is pulled out, which can effectively support and guide the cover 13 in the open state and prevent it from falling.
[0046] An opening stroke limit seat 10 is provided on one side of the frame. When the cover 13 is opened, the outer end of the cover 13 abuts against the opening stroke limit seat 10, thereby limiting the opening stroke of the cover 13.
